To play music loud enough that other people can hear it, particularly in a public location. [Sod + -cast.]
Just a few days ago I was treated to a speech on this theme by a cab driver, whose list of grievances included the neglect of hand signals by people riding Boris bikes and the prevalence of sodcasting (playing loud music through a phone"s less than sweet-sounding speaker) on the train.

When times are good, a community can just about cope: lack of empathy leads to nothing worse than the rudeness of sodcasting on buses, the discharging of one"s nostrils on to a pavement, the casual dropping of a takeaway food container into the doorway of someone else"s flat.
—Graeme Archer, “Empathy has fled the inner city, and it"s time for me to follow,“ The Telegraph, December 9, 2011
Music, on a crowded bus, coming from the speaker on a mobile phone. Sodcasters are terrified of not being noticed, so they spray their audio wee around the place like tom cats.

The British slang term sod has many meanings and uses, but in this context it refers to a person who is an idiot or a jerk.
